This invention relates to a pessary of the kind comprising an inflatable member fitted with a conical retaining flange and having an outside pocket for the reception and ejection of medicaments, and its object is to provide means for ensuring a safe delivery of the medicaments against and into the womb.

The object is achieved according to the invention by mounting, on a circumferentially resilient cushion, a dome-shaped cap of soft rubber having in its most prominent portion a centrally disposed inlet and discharge aperal elevation.

Fig. 2 is a central longitudinal section of the pessary.

Fig. 3 is a plan elevation of same.

The improved pessary possesses an air cushion a, which is provided at the center of its bottom 5 with a tubular extension 0 terminating in a tube d of small diameter, which serves for inflating the air cushion a.

Ooncentrically surrounding the tubular extension 0 at some distance from it an annular collar 6 is fixed to the bottom I) of the cushion a so as to form a firm basis for same. A rim f in the shape of a truncated cone is attached with its narrow end to the bottom 6 of the cushion a inside the annular collar e, so that it adheres thereto, the rim f in combination with the bottom I) of the cushion a forming an inverted cup.

The cushion a carries on its top a domeshaped cap 9 having an aperture h at its apex. The space enclosed by the cap 9 and the top of the cushion a serves to confine a disinfectant paste or a medicament suitable in the application of the pessary.

The cushion a with its tubular extension 0 and the tube (1, the annular collar e, the rim f and the dome-shaped cap 9 are formed of soft rubber of suitable. flexibility, elasticity and stability, the collar 6 beingeither hollow or of solid construction.

The pessary in its application is inserted in the vaginal passage with the filled up cap 9 in front. The cap g, being dome-shaped, facilitates the insertion of the pessary, which reaches the required position, when the cap abuts against the womb. Byconing the wearer, the rim 7 in engaging the walls of the vagina safeguarding the tight fitting of the pessary inside the vagina.

The cushion 6 may be inflated with air under atmospheric or higher pressure, the air contained in the cushion being secured therein by tying an airtight knot z' in the tube d which serves for inflating the cushion.

While I have shown in the accompanying drawing the preferred form of my invention it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claim, or of equivalents to the structure set forth.

What I do claim as my invention and desire to secure by Letters Patent is:

A pessary of the character described, comprising a circumferentially resilient cushion, a conical retaining flange on said cushion, and a dome-shaped capof soft rubber having in its most prominent domed portion a centrally disposed inlet and discharge aperture, the cushion carrying the cap at one side and the flange at the other side, all in symmetric positions.
